__init__(self, interval=None, callbacks=None)

Parameters

interval : int, default: 1000ms

The time between timer events in milliseconds. Will be stored as timer.interval .

callbacks : list[tuple[callable, tuple, dict]]

List of (func, args, kwargs) tuples that will be called upon timer events. This list is accessible as timer.callbacks and can be manipulated directly, or the functions add_callback and remove_callback can be used.

Examples

See :

Local connectivity graph

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.

Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)

SVG is more flexible but power hungry; and does not scale well to 50 + nodes.

All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
